Here is my wide-ranging conversation with Mike Williamson, one of the first seaweed farmers in north America and the CEO of Cascadia Seaweed, one of the largest provider of ocean cultivated seaweed in North America (full bio below).

He told me some really compelling stories about starting as a pioneer seaweed farmer and entrepreneur in British Columbia (Canada). Cascadia Seaweed decided early on to start farming their own seaweed and then focus on 3 main verticals: seaweed for making plant-based food products (e.g. seaweed snacks), feed additives for cows to reduce greenhouse gas emissions, extracting chemicals and dietary supplements from seaweed in a sustainable way.

We looked into the importance of scale and the role of small businesses in the seaweed industry, with some great advice for seaweed entrepreneurs.

Mike shared his experience and learnings with the branding aspects of developing seaweed products, testing them and bringing them to market - covering topics such as changing people perception and expanding the consumer acceptance and awareness of seaweed.

We then launched into a deep dive around seaweed processing: from harvesting, freezing and extracting ingredients (bio-refining). He explained how seaweed doesn’t behave like any other land-based vegetables and the challenges that this brings to the processing stages, creating a need for specialised machinery and innovation in this area, which is strongly supported by collaboration with other seaweed entrepreneurs.
